mysql无法启动，我看不到为什么

Question

重新启动后，mysql无法启动。在我重新启动之前，我与/etc/mysql/my.cnf文件混在一起，试图将我的默认字符编码从utf-8更改为latin1。据我所知，我已经取消了我的改变（认为他们可能是它未能开始的结果），但我不确定，因为我没有做出备份（愚蠢）。

我怎么看到为什么mysql无法启动？我认为它会输出一些信息给/var/log/mysql.err或/var/log/mysql.log，但这些文件中没有任何内容。是否有其他文件可能会记录该问题，或者我可能会以详细/跟踪模式启动它以输出问题？我现在正在查看man文件，但看不到任何有用的信息（尽管我可能正在查看错误的man文件）。

这是我的/etc/mysql/my.cnf文件的内容，因为目前的情况是，希望有人能发现明显错误的东西：

我尝试过各种的my.cnf文件并没有什么工作，所以我最终从头开始重新安装它，这似乎也解决了我的latin1/utf8问题。所以没有问题了，谢谢阅读。
